Txiav cov ntsiab cai ntawm cov ntaub ntawv yas
Qhov zoo tshaj plaws feature ntawm plastics nyob rau hauv kev ua tau zoo yog nws cov tsis nruj nruj thiab yooj yim khoov thiab deformation. Tsis tas li ntawd, cov thermoplastics kuj muaj cov thermal conductivity tsis zoo thiab yooj yim rau cua sov thiab muag muag. Tag nrho cov no tau ua rau qee qhov nyuaj hauv kev txiav.
Thaum txiav cov yas ua haujlwm, nws yog qhov zoo tshaj plaws los siv cov cuab yeej siv high-speed steel lossis cemented carbide, nrog tus nqi pub ntawm 0.1 mus rau 0.5 hli rau ib lub kiv puag ncig thiab kev txiav ceev dua. Rau qhov teeb meem ntawm kev tsim hluav taws xob hauv kev ua haujlwm, lub cuab yeej pem hauv ntej lub kaum sab xis ntawm 10 degrees txog 30 degrees thiab lub cuab yeej rov qab lub kaum sab xis ntawm 5 degrees txog 15 degrees tuaj yeem siv. Ntev npaum li lub cuab yeej ntse txaus, nws tuaj yeem tsim cov chips banded thiab tshem tawm feem ntau ntawm cov cua sov. Tsis tas li ntawd, compressed cua kuj siv tau los ua kom txias txias. Tsuas yog cov khoom siv celluloid yog qhov zam. Vim tias nws yooj yim rau ntes hluav taws thaum txiav, nws yuav tsum tau txias nrog dej.
Thaum lub sij hawm machining, yog tias cov chips luv luv thiab plua plav tau tsim tawm, cov cuab yeej yuav dhau los ua qhov tsis zoo thiab ua paug rau lub tshuab cuab yeej. Cov khoom raug nthuav tawm thiab cov lus qhia ntawm cov cuab yeej siv tshuab yog qhov yooj yim tshaj plaws rau cov pa phem, yog li lawv yuav tsum tau tiv thaiv.
Tig cov ntaub ntawv yas
Cemented carbide txiav cov cuab yeej tsim nyog rau kev tig cov yas, thiab kev txiav ceev sib txawv nrog cov thermosetting yas thawv thiab cov thermoplastic. Thaum tig cov thermosetting yas xws li phenolic yas, amino yas thiab nplaum daim kab xev, txiav ceev yuav tsum yog 80 mus rau 150 meters ib feeb; Thaum tig PVC, nylon, bakelite thiab lwm yam thermoplastics, txiav ceev yuav tsum yog 200 mus rau 600 meters ib feeb.
Milling cov ntaub ntawv yas
Thaum milling plastics, yog siv high-speed steel cutters, milling ceev feem ntau yog 35 mus rau 100 meters ib feeb; Yog tias siv cov cuab yeej cemented carbide, milling ceev tuaj yeem nce 2 mus rau 3 zaug. Yog li ntawd, cov cuab yeej cemented carbide yog qhov kev xaiv zoo dua.
Drilling ntawm cov ntaub ntawv yas
Rau cov yas drilling, lub khob cij twist laum nrog lub kaum ntse ntse loj tuaj yeem siv tau, thiab thaum lub qhov taub loj dua 30mm, yuav siv lub tshuab ua zes. Vim qhov pom kev nthuav dav ntawm cov yas, thaum lub laum me ntsis tshem tawm tom qab qhov drilling, lub qhov taub feem ntau shrinks, uas yog me dua li txoj kab uas hla ntawm lub laum ntsis. Yog li ntawd, txoj kab uas hla ntawm lub laum me ntsis siv yuav tsum loj dua li qhov xav tau aperture, thiab qhov nce yog feem ntau ntawm 0.05 thiab 0.1 hli. Thaum siv cov khoom siv high-speed steel, qhov kev txiav ceev yog nruab nrab ntawm 40 thiab 80 meters ib feeb. Thaum drilling, ib daim ntawm cov ntoo tawv tawv yuav tsum muab tso rau hauv qab ntawm cov yas kom tiv thaiv cov yas los ntawm kev poob ntawm lub qhov phab ntsa ntawm lub qhov hluav taws xob ntawm qhov laum.
Lwm txoj kev txiav cov ntaub ntawv yas
Feem ntau, cov txheej txheem ntawm kev npaj thiab slotting yuav tsum tsis txhob siv rau cov yas, vim tias qhov kev txiav ceev ntawm ob txoj kev no tsawg dhau. Tab sis qee zaum koj kuj tuaj yeem siv woodworking planer rau leveling thiab chamfering. Thaum tapping yas, high-speed steel hlau cones nrog dav grooves yuav siv tau, thiab xyuam xim rau lub lubrication ntawm nug nqe lubricating roj; Sab nraud threads tuaj yeem txiav nrog ib tug xov comb.
Rau cov thermosetting plastics xws li nylon, bakelite thiab bakelite, lawv tuaj yeem ua hauv av nrog xoob dawb corundum lossis silicon carbide sib tsoo log, lossis polished nrog cov ntaub abrasive, tab sis lawv yuav tsum tau txias nrog dej. Txoj kev sib tsoo feem ntau tsis pom zoo rau kev ua cov thermoplastic vim tias cov khib nyiab sib tsoo yooj yim los thaiv lub log sib tsoo.
